ABB – NTAC-02 – Pulse Encoder Interface Module, 24 V DC, 7.5 W / 300 mA

The ABB NTAC‑ is a pulse encoder interface module—an accessory option/SP kit designed to connect incremental encoders (ABZ signals) to ABB frequency converters (e.g., ACS). It provides selectable  V or  V encoder supply and interfaces encoder feedback into the drive’s digital control inputs.

Key Features:

• Manufacturer: ABB (Asea Brown Boveri)  

• Model / P/N: NTAC‑ (also known as NTAC‑‑KIT, )  

• Function: Encoder pulse interface module for pulse-to-drive integration  

• Power & Supply:  V DC ±%, . W,  mA; jumper-selectable  V or  V encoder supply  

• Inputs: Channels A, B, Z with shielded encoder cable support; up to  kHz pulse rate  

• Connectivity: Plug-in accessory to ABB frequency converters / drives

• Compatibility: ACS and other ABB drives requiring pulse encoder interface; NTAC‑ and NTAC‑ are not interchangeable
